Information technology

The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones.

History of computer technology

Devices have been used to aid computation for thousands of years, probably initially in the form of a tally stick. The Antikythera mechanism, dating from about the beginning of the first century BC, is generally considered to be the earliest known mechanical analog computer, and the earliest known geared mechanism.

Data storage

Early electronic computers such as Colossus made use of punched tape, a long strip of paper on which data was represented by a series of holes, a technology now obsolete. Electronic data storage, which is used in modern computers, dates from World War II, when a form of delay line memory was developed to remove the clutter from radar signals, the first practical application of which was the mercury delay line.

Databases

Database management systems emerged in the 1960 to address the problem of storing and retrieving large amounts of data accurately and quickly. One of the earliest such systems was IBM's Information Management System (IMS), which is still widely deployed more than 40 years later. IMS stores data hierarchically,

Academic perspective

In an academic context, the Association for Computing Machinery defines IT as "undergraduate degree programs that prepare students to meet the computer technology needs of business, government, healthcare, schools, and other kinds of organizations ....

Antbo is the robot ant to learn about robotics

 
Really, teaching computer programming seems to be the number 1 priority of the new entrepreneurs of robotics. After monthly box Robobox after Codeybot and after Root, class robot, it is the turn of Antbo, the robot ant made its appearance in the field of recreational and educational robot.
In 2014, DFRobots, a young Chinese company based in Shanghai, launched the idea of ​​a companion robot to learn programming. In January 2016, the team was testing the components of the final product. And early April, the crowdfunding campaign on Indiegogo was launched.
Antbo (Ant-bot), thus born of the desire to share the art of computer programming, with the younger but not only. It is intended for all ages and is meant to be fun and easy to manipulate to make accessible robotics and programming. Installation in less than an hour, you can immediately get started in programming. For 223x125x152 mm and 209 grams, the robotic insect is particularly handy. But it is also removable and customizable. It is possible you change parts or add more features forever. Can be directed by the pre-programmed commands, remote control or even by voice and in a radius of at least 15 meters. But it is also able to explore their environment by itself thanks to its sensors and its system composed of 30 neurons.




Another important point Antbo is compatible with multiple platforms. So you can program your robot on Scratch, Arduino or Whendo. The small Chinese robot is so different from his colleagues who are often compatible with some platforms.

Antbo is already available for pre-sale on Indiegogo page of the company, for the sum of $ 69 only (against the $ 150 and more Codeybot). The creators of the robot ant have not yet met that $ 7,000 of the required 50,000, or 14%. You have a month to order your Antbo before the crowdfunding campaign closes. The first delivery scheduled in the month of November.

Orange has deployed 100,000 kilometers of fiber

Orange has deployed 100,000 kilometers of fiber ,4G Deployment : Orange and Bouygues still leading
The sporting event is to be a technological showcase for the incumbent, in terms of high speed fixed and mobile.
Forced to turn the page Bouygues Telecom, Orange now move on and prepares for Euro 2016, major event of football but also technology. As the incumbent operator, the leader in optical fiber and 4G, the group has no room for error.
One thing is certain, Orange has every chance of his side to demonstrate its expertise and make this competition which takes place in France a technology showcase for high speed fixed and mobile.

4 years of work

No less than four years of work were needed to prepare the event. The data provide dizzy: 100. 000 kilometers of optical fiber have been deployed in stages, twice around the Earth to ensure optimal transmission of data, especially for the hundreds of media present. 220 TV channels will be based on the Orange network to transmit the matches. In terms of flows, Orange promises more than 2 terabits per second for ten stages, never seen.
It also has 680 Wi-Fi hotspots to more than 110,000 concurrent connections. 4G has not been forgotten with a densification of antennas: Some stadiums will count 132, allowing viewers to surf without a hitch.
"An event like this is a technical feat," said Stéphane Richard, CEO of the operator. It is also a strategic moment in terms of image for Orange and indirectly to its business.

Samsung Galaxy Tab Pro S

 Samsung Galaxy Tab Pro S ,Windows 10: Microsoft relaunches för iOS Bridge project
The new Samsung Galaxy Tab Pro S takes the name of the product range Android while running Windows 10. This hybrid model is the latest in a long series of terminals seeking to create a Windows tablet that either both useful, intuitive and attractive. It is Microsoft that has most approached this ideal compromise with its Surface range which over four generations has become a great product.
We could recommend the Surface Pro 4 as the Windows tablet reference, but it has a major flaw: it is expensive. This is because the protective keyboard cover, which is essential for everyday use, is sold separately. Result, the base price is 999 euros to which add 149 euros for the Type Cover.
The Galaxy S footprint TabPro the best area while correcting some of its shortcomings. The most important information is that Samsung offers a model equipped with an AMOLED screen 12 inches with an Intel Core m3, 128 GB SSD and above the protective keyboard cover for 950 euros. An effort which we welcome as a sign of respect towards consumers.
Although it offers excellent value for money, the S TabPro however, is not perfect. The keyboard has a nice clear impression of strength, it is not as advanced as that of the Surface Pro 4. In this latest version, Microsoft has opted for chicklet keys that are similar to those found on keyboards of laptops while the Samsung keyboard is equipped with flush buttons without spaces that are much less ergonomic. Operation is noisy compared to the sweetness of the keyboard area, which may explain why Microsoft invoice 149 euros.
One like the other use a magnetic connection system with the screen that is reassuring. The Samsung model protects both the front and back of the tablet while the keyboard-cover the area only covers the screen. In terms of ergonomics, there is an area in which the Galaxy S TabPro beats the Surface Pro 4 and another in which he is outclassed.
Without the protective cover, the tablet portion of the TabPro S is incredibly thin and light with 689 grams on the scale against 798 grams for the Surface Pro 4. But the area incorporates a swivel foot that allows positioning the screen almost n 'any angle.
This is a huge advantage over the S TabPro that do not have integrated foot and uses his sleeve to offer only two screen positions: one almost right and the other much more tilted back . Neither of them seemed to us perfectly in our tests of various positions on desks and chairs. However, the low position be well enough when one is sitting in a couch with tablet on his lap. Those who feel comfortable with both positions thoughts by Samsung engineers lucky. For others, not having more freedom of adjustment is a real downer.
Another difference is the pen that Microsoft includes with the surface while Samsung sells it separately. Its release was delayed and has not yet information on its availability in France. We could try it briefly at the press presentation and it seemed rather efficient for drawing and sketches.
Apart from its keyboard comes home, the biggest advantage of TabPro S is its AMOLED pixels 2.160x1.440 that the Korean brand already uses on many of its smartphones. The result is breathtaking with a clear image even clear and bright under the most extreme angles.
One of the reasons that Samsung may propose a keyboard-cover and an AMOLED screen for less than 1,000 euros is the choice of a Core processor Intel m3 which is not as powerful as Core i5 or i7 that found on most computers. This is the second generation of Core M that progresses performance level and autonomy from the first generation that was pretty disappointing (especially present in the MacBook 12-inch).
In common usage, the processor has made the grade for web browsing, playing videos in high definition, but the system could sometimes jerky. However, good flow by using the new Microsoft Edge browser that is optimized for Windows 10. The range of the Surface Pro 4 entry model is also equipped with a Core m3 chip is stored, but Microsoft offers other configurations Core i5 and Core i7.
The autonomy of the S TabPro were pleasantly surprised, especially beating the Surface Pro 4 and the 12-inch MacBook. She held 9h23mn our online video streaming test, which is ample for a full day of work. It is also 4 times better than the Surface Pro 4.
Conclusion
The TabPro Samsung S is not perfect, but its few flaws serve a just cause: to offer a high-end Windows tablet for a reasonable price. The price / quality ratio is excellent especially considering the Amoled screen and long battery life. But the main argument is the presence of a keyboard-cover supplied as standard makes this product far more useful out of the box. And the goal is not it precisely to offer users useful tools?

Robird is the robot raptor Clear Flight Solutions soon take flight

 Robird is the robot raptor Clear Flight Solutions soon take flight
The birds are real wounds for many professionals. They peck farmers' fields, waste reception invest and endanger some flights, besides excrement they leave almost everywhere. A Dutch company could well have found the solution with Robird. The robotic falcon model of Clear Flight Solutions should beat first wings to Weeze airport, Germany.
"We solve problems by combining the power of nature to new technologies." That one sentence ambition of Clear Flight Solutions (CFS), a spin-off company of the University of Trent, the Netherlands. Robirds the CFS offer their services in four main areas: agriculture, waste management, airports and ports.
"We have already stolen our Robirds and our drones in many places, but do it in an airport, it is a first" said Nico Nijenhuis, CEO of the company. A step even more crucial that the Clear Flight Solutions engineers had to overcome a number of strengths, including Schipol airport "who was interested for several years, but the Dutch laws prevent us from conducting tests. This is easier in Germany, which is why we finally opted for Weeze airport "he explains.
Very surprising reluctance given that Schipol airport is already conducting tests to integrate KLM service robots. The fact remains that the Netherlands have made the fight against drones a priority. The Dutch authorities have already developed drones to capture unauthorized flying machines. More surprisingly, the police also trained eagles to attack these harmful drones or criminals. Practical reasons also favored the choice of Weeze Airport. It receives only 2.5 million passengers per year, against 55 million for Schiphol Airport. An air mess in which it is difficult to make room for newcomers.
In this airport, mission eagles and hawks CFS will be to the policeman and away the many birds that find refuge in these great open spaces. The aim is to avoid possible air disasters. For if the drones are collisions with aircraft makers, is the birds that we must take in the overwhelming majority of cases. Remember the spectacular landing of an A320 on the Hudson right in New York, in 2009. An emergency landing caused by a collision ... with a flock of geese. The Robird CFS is so well designed that perfectly imitates the flight of a bird of prey, so that the birds decamp immediately, as smart as they are to overcome the various control systems implemented by airports ( and that would cost billions of dollars annually worldwide). A new biomimetic device that has proven itself.
And because, according to CFS, when introducing a predator in an ecosystem, it is the system to adapt to this new element. Under the supervision of robotic raptors, volatile population in a given area, shows a decrease of 50%. The benefits of a true falcon, with those of a replica: the robotic falcon does not effectively chase the birds, they will go instinctively to its territory.
Rest assured, the mission of Clear Flight Solutions is not to eradicate the bird population of the planet surface. In a greener register, the company also offers drones to inspect certain areas such as the Province of Overijssel, in search of water birds whose population unfortunately cease to fall.
